[0002] Automated Mechanical Transmission (AMT) has the advantages of simple structure, high transmission efficiency and low cost, and is widely used in commercial vehicles. During vehicle driving, AMT performs gear shifting operations. The greater the mileage of the vehicle, the higher the possibility of AMT failure and the more serious the wear of parts. Therefore, it is necessary to accurately and reliably analyze the gear shifting performance of the vehicle AMT, so as to timely understand the health status of AMT and ensure driving safety.
[0003] In the related art, the shifting performance is usually analyzed by counting the shifting time of the AMT, but the performance analysis results are inaccurate and have low precision. Therefore, in order to further analyze the hardware control performance and provide reference for the subsequent optimization of indicators such as shifting time and shifting smoothness, the action time of each component in the AMT during the shifting process (such as the shifting time of the front and auxiliary boxes) also needs to be counted. Usually, the action time of each component in the AMT is counted manually, which has high labor costs and low efficiency. Summary of the invention

[0057] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0058] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.
[0059] Figure 1 1 is a schematic diagram of an implementation environment according to an exemplary embodiment. The implementation environment may include a first vehicle 110, a telematics service provider (TSP) cloud platform 140, and a data analysis platform 150. The first vehicle 110 and the TSP cloud platform 140, and the TSP cloud platform 140 and the data analysis platform 150 may communicate via various wired or wireless methods, such as but not limited to: 4G network, 5G network, WiFi, etc.
[0060] The first vehicle 110 sends the operating parameters under daily operating conditions to the TSP cloud platform 140 through its own telematics processor (T-BOX) for storage. After receiving the statistical instruction, the data analysis platform 150 obtains the operating parameters from the TSP cloud platform 140. In one embodiment, the data analysis platform 150 and the TSP cloud platform 140 can be independent devices, such as servers. Figure 1 As shown. In other embodiments, the data analysis platform 150 can be integrated on the TSP cloud platform 140 in the form of software. After the data analysis platform 150 obtains the operating condition parameters, the vehicle AMT shift data statistics are performed through computer software. The vehicle AMT shift data statistics method provided in the present disclosure can be applied to the data analysis platform 150.
[0061] Figure 2 FIG. 1 is a flow chart of a vehicle AMT shift data statistics method provided by an exemplary embodiment. Figure 2 As shown, the method includes the following steps.
[0062] In step S101 , in response to receiving a statistical instruction input by a user, operating parameters of a target vehicle within a specified period of time are obtained.
[0063] The statistical instruction can be input by the user. For example, the output dialog box "Do you want to perform statistical analysis?" can be controlled on the computer display screen. The user can click the "Yes" button with the mouse or keyboard (such as the Enter key) to send the statistical instruction. The target vehicle and the specified time period can be preset by the user. For example, a vehicle selection dialog box and a time period selection dialog box can be displayed on the computer display screen, and the user can select the target vehicle and the specified time period with the mouse. The target vehicle can be a single vehicle. After receiving the statistical instruction, the data analysis platform can obtain the operating parameters of the target vehicle within the specified time period.
[0064] In step S102, a time period during which a gear shift occurs within a specified time period is identified according to operating condition parameters.
[0065] After the operating condition parameters are obtained, the operating condition parameters may be preprocessed. For example, invalid data may be filtered out and operating condition parameters that are in a shift state at the start or end of sampling may be deleted, as well as operating condition parameters with the same sampling points at similar times may be deleted.
[0066] There are differences in the operating parameters of the vehicle AMT before and after the gear shifting process, so the time period in which the gear shifting occurs within the specified time period can be identified based on the operating parameters of the target vehicle within the specified time period. The AMT of the target vehicle may perform one or more gear shifts or may not perform any gear shifts within the specified time period, so the identification result of the time period in which the gear shifting occurs within the specified time period may include one or more time periods in which the gear shifting occurs or may not include the time period in which the gear shifting occurs.
[0067] The specified time period may be, for example, a shorter time period in minutes, such as from 11:30 am on March 11, 2024 to 11:40 am on March 11, 2024.
[0068] In step S103, a characteristic time period within each time period during which a gear shift occurs is identified according to the operating condition parameters.
[0069] The characteristic time period is a time period during which the gear shift occurs that can characterize the gear shift action time of each component of the AMT, for example, the front auxiliary gear shift time period. After identifying the gear shift time period during the specified time period, for each of the one or more gear shift time periods, the characteristic time period of each gear shift time period is further identified based on the operating condition parameters.
[0070] In step S104, according to the recognition result, the shift data of the AMT of the target vehicle within a specified period of time is counted.
[0071] After identifying the time period during which the target vehicle shifts gears within the specified time period and the characteristic time period of each time period during which the gear shift occurs, the gear shift data of the AMT of the target vehicle within the specified time period can be counted according to the determined time period during which the gear shift occurs and the characteristic time period of each time period during which the gear shift occurs. The gear shift data may include, for example, the gear shift duration, the number of gear shifts, the front auxiliary gearbox gear shift duration, etc.
[0072] After the shift data is counted, the shift data can be stored. Exemplarily, the shift data can be sent to a storage unit, and the shift data can be stored in the storage unit in the form of a data table.
[0073] Through the above technical solution, in response to receiving the statistical instruction input by the user, the operating parameters of the target vehicle within the specified time period are obtained, and the time period in which the gear shift occurs within the specified time period is identified according to the operating parameters. According to the operating parameters, the characteristic time period in each time period in which the gear shift occurs is identified, and according to the identification result, the gear shift data of the AMT of the target vehicle within the specified time period is counted. After receiving the statistical instruction, according to the operating parameters of the target vehicle within the specified time period, the time period in which the gear shift occurs within the specified time period can be automatically identified without manual analysis, and then the time period in which the gear shift occurs is subdivided in combination with the operating parameters to obtain the characteristic time period (the characteristic time period represents the gear shift action time of each component of the AMT). In this way, combined with the identification result, the gear shift data of the AMT of the target vehicle within the specified time period can be quickly and accurately counted, thereby improving the efficiency of counting the gear shift data of the vehicle AMT, saving manpower, and making the analysis method more intelligent.
[0074] In yet another embodiment, the step of identifying the time period during which the gear shift occurs within the specified time period according to the operating condition parameters includes:
[0075] From the start time of the specified time period, or from the shift completion time of the last shift event, the time corresponding to the operating condition parameters satisfying the shift start condition is determined as the shift start time;
[0076] From the start time of the gear shift, the time corresponding to the operating condition parameters that meet the gear shift completion conditions is determined as the gear shift completion time, where:
[0077] If this gear shift event is the first gear shift event within the specified time period, the gear shift start time of this gear shift event is the first gear shift start time determined from the start time of the specified time period; if this gear shift event is not the first gear shift event within the specified time period, the gear shift start time of this gear shift event is the first gear shift start time determined from the gear shift completion time of the previous gear shift event.
[0078] The specified time period may include one or more gear shifting events. The gear shifting event may be the first gear shifting event in the specified time period, or may not be the first gear shifting event in the specified time period. Therefore, the gear shifting start time may be determined from the starting time in the self-defined time period, or may be determined from the gear shifting completion time of the previous gear shifting event.
[0079] After the gear shift start time is determined, when the gear shift completion time is determined, it can be determined that the current gear shift event is completed.
[0080] Figure 3 FIG. 1 is a schematic diagram of shifting event classification provided by an exemplary embodiment. Figure 3 As shown, the start time G1 of the specified time period is 10:01:00, and the end time G8 of the specified time period is 10:02:00. Three shift start times are determined within the specified time period, namely, the shift start time G2 (10:01:05), the shift start time G4 (10:01:32), and the shift start time G6 (10:01:50), the three shift completion times are respectively, namely, the shift completion time G3 (10:01:06), the shift completion time G5 (10:01:34), and the shift completion time G7 (10:01:51), and the three shift events are respectively, namely, the shift event A, the shift event B, and the shift event C. Among them, the gear shift event A is the first gear shift event in the specified time period 10:01:00-10:02:00, then from the start time G1 (10:01:00) of the specified time period, the first gear shift start time G2 (10:01:05) determined is the gear shift start time of the gear shift event A, and the gear shift completion time G3 (10:01:06) is the gear shift completion time of the gear shift event A; the gear shift event B is the second gear shift event in the specified time period, therefore, the gear shift start time of the gear shift event B is the gear shift completion time G3 (10:01 :06), the first gear shift start time is determined, that is, the gear shift start time G4 (10:01:32), and the gear shift completion time of the gear shift event B is the gear shift completion time G5 (10:01:34); the gear shift event C is the third gear shift event in the specified time period, thus, the gear shift start time of the gear shift event C is the first gear shift start time determined since the gear shift completion time G5 (10:01:34) of the previous gear shift event B, that is, the gear shift start time G6 (10:01:50), and the gear shift completion time of the gear shift event C is G7 (10:01:51).
[0081] For example, after determining the time period in which the gear shift occurs, it can be determined whether a supplementary gear shift occurs in each time period in which the gear shift occurs. For each time period in which the gear shift occurs, if a supplementary gear shift signal of the sliding gear sleeve and a supplementary gear shift signal of the front auxiliary box are identified from the time when the gear shift starts to the time when the gear shift is completed, it is determined that a supplementary gear shift occurs in the time period in which the gear shift occurs.
[0082] In this embodiment, the shift start time and shift completion time of each shift event within a specified period are determined by the above method, which has good reliability and high accuracy.
[0083] In yet another embodiment, the operating condition parameters include: gear information;
[0084] The gear shift start conditions include: the target gear position at the current moment is different from the target gear position at the previous moment;
[0085] The gear shift completion conditions include: the gear position at the current moment is different from the target gear position at the current moment and the gear position at the next moment is the same as the target gear position at the next moment;
[0086] The above-mentioned identification of characteristic time periods within each time period during which a gear shift occurs based on the operating condition parameters includes:
[0087] determining a shift type for a period during which a shift occurs;
[0088] According to the operating condition parameters, a characteristic time period corresponding to the shift type of the time period in which the shift occurs is identified.
[0089] The gear information may be, for example, first gear, second gear, etc. If the target gear at the current moment is different from the target gear at the previous moment, and the vehicle AMT needs to change from the target gear at the previous moment to the target gear at the current moment (for example, the target gear at the previous moment is second gear, and the target gear at the current moment is third gear), then it can be determined that the gear shift has started, and the current moment is determined as the gear shift start time;
[0090] When the gear position at the current moment (for example, fourth gear) is different from the target gear position at the current moment (for example, fifth gear) and the gear position at the next moment (for example, fifth gear) is the same as the target gear position at the next moment (for example, fifth gear), it can be considered that the vehicle has completed gear shifting and the current moment is determined as the gear shifting completion moment.
[0091] There are many types of gear shifting of AMT, such as neutral to gear, gear to neutral, etc. Gear can be any gear except neutral. Different gear shifting types have different gear shifting actions of AMT, and different gear shifting actions correspond to different characteristic time periods. Therefore, the characteristic time period corresponding to the gear shifting type of the time period when the gear shifting occurs is further identified according to the working condition parameters.
[0092] In this embodiment, the gear-engagement start condition and gear-engagement completion condition can be used to quickly and accurately determine the gear-engagement start time and gear-engagement completion time. In addition, the characteristic time period corresponding to the gear shift type of the gear shifting period is identified according to the operating condition parameters, which has good flexibility and further improves the accuracy of the characteristic time period, which is beneficial to the subsequent performance analysis.
[0093] In yet another embodiment, the shift types include neutral to in-gear and in-gear to in-gear, and the shift type of the time period in which the shift occurs is determined as follows:
[0094] If the gear position at the start time of the gear shift in the time period when the gear shift occurs is neutral and the target gear position is not neutral, then the gear shift type in the time period when the gear shift occurs is determined to be neutral to gear;
[0095] If the gear position at the gear shift start time of the gear shift period is not neutral and the target gear position is not neutral, it is determined that the gear shift type of the gear shift period is in-gear to in-gear.
[0096] The gear shift type may include two types: neutral to gear and gear to gear. Neutral to gear is to shift from neutral to any gear except neutral, and gear to gear is to shift from the current gear (any gear except neutral) to any gear except the current gear and neutral.
[0097] When the gear position at the start time of the gear shift in the gear shift period is neutral and the target gear position is not neutral, it can be considered that the vehicle is about to shift from neutral to any gear except neutral, and the gear shift type is determined to be neutral to gear.
[0098] When the gear position at the start time of the gear shift in the period when the gear shift occurs is not neutral and the target gear position is not neutral, it can be considered that the vehicle is about to change from the current gear position (any gear position except neutral) to any gear position except the current gear position and neutral, and the gear shift type in the period when the gear shift occurs is determined to be in gear to in gear.
[0099] In this embodiment, the shift type of the time period in which the shift occurs can be determined reliably and accurately through the above conditions.
[0100] In another embodiment, the operating condition parameters include: a front auxiliary gear shift solenoid valve state signal, an intermediate shaft brake solenoid valve state signal and a gear shift progress signal; when the gear shift type is from neutral to gear, the characteristic time period includes a clutch release time period, a front auxiliary gear shift time period, an intermediate shaft brake time period and a main gear shift time period;
[0101] The above-mentioned identifying, according to the operating condition parameters, a characteristic time period corresponding to the shift type of the time period in which the shift occurs includes:
[0102] If it is identified that the front auxiliary gearbox shift solenoid valve is in the open state, it is determined that there is a front auxiliary gearbox shift, and the time from the opening of the front auxiliary gearbox shift solenoid valve to the opening of the intermediate shaft brake solenoid valve is determined as the front auxiliary gearbox shift period, and the time from the shift start time of the current shift period to the opening of the front auxiliary gearbox shift solenoid valve is determined as the clutch release period;
[0103] If the front auxiliary gearbox shift solenoid valve is always in the closed state, it is determined that there is no front auxiliary gearbox shift, and it is determined that there is no front auxiliary gearbox shift period, and the shift start time of the current shift period to the intermediate shaft brake solenoid valve opening time is determined as the clutch release period;
[0104] The time from when the intermediate shaft brake solenoid valve is turned on to when the gear shift process signal is switched to the gear shifting state signal is determined as the intermediate shaft braking period;
[0105] The time from when the shift progress signal is switched to the shifting state signal to when the shift is completed during the current shifting period is determined as the main transmission shifting period.
[0106] The operating condition parameters may include, for example, a state signal of the front auxiliary box shift solenoid valve, a state signal of the intermediate shaft brake solenoid valve, and a shift progress signal. The state signal of the front auxiliary box shift solenoid valve may include an open state and a closed state. The state signal of the intermediate shaft brake solenoid valve may include an open state and a closed state. The shift progress signal may include, for example, an in-gear state, a retracting state, an out-of-gear state, and an in-gear state.
[0107] When the shift type is from neutral to gear, the clutch, front auxiliary box, intermediate shaft and main box of the AMT participate in the shift process. Therefore, the shift event (the time period when the shift occurs) from neutral to gear includes the characteristic time periods of clutch separation time period, front auxiliary box shift time period, intermediate shaft braking time period and main box shift time period. Therefore, the clutch separation time period, front auxiliary box shift time period, intermediate shaft braking time period and main box shift time period in the time period from neutral to gear can be identified according to the front auxiliary box shift solenoid valve state signal, the intermediate shaft brake solenoid valve state signal and the shift process signal.
[0108] In this embodiment, the above conditions can reliably and accurately identify the clutch disengagement period, the front auxiliary gear shift period, the intermediate shaft braking period and the main gear advance period within the shift period from neutral to gear.
[0109] In another embodiment, the operating condition parameters include: a front auxiliary gear shift solenoid valve state signal, an intermediate shaft brake solenoid valve state signal and a gear shift progress signal; when the gear shift type is in-gear to in-gear, the characteristic time period includes a main gear shifting time period, a front auxiliary gear shifting time period, an input shaft speed-up time period, an intermediate shaft braking time period and a main gear shifting time period;
[0110] The above method of identifying the characteristic time period corresponding to the shift type of the time period in which the shift occurs according to the operating condition parameters further includes:
[0111] If the shift progress signal switches to the gear-disengaging state signal, it is determined that the main gearbox is disengaging, and the time when the shift progress signal switches to the gear-disengaging state signal to the time when the shift progress signal switches to the out-of-gear state signal is determined as the main gearbox disengaging period;
[0112] If the gear-shifting state signal is not identified, it is determined that there is no main gearbox gear-shifting period;
[0113] If it is identified that the front auxiliary gearbox shift solenoid valve is in the open state, it is determined that there is a front auxiliary gearbox shift, and the time from the front auxiliary gearbox shift solenoid valve opening time to the time when the shift signal is switched to the in-gear state signal is determined as the front auxiliary gearbox shift period;
[0114] If the front auxiliary gearbox shift solenoid valve is always in the closed state, it is determined that there is no front auxiliary gearbox shift and there is no front auxiliary gearbox shift period;
[0115] The time from when the shift progress signal is switched to the out-of-gear state signal to when the intermediate shaft brake solenoid valve is turned on is determined as the input shaft speed-up period;
[0116] The time from when the intermediate shaft brake solenoid valve is turned on to when the gear shift process signal is switched to the gear shifting state signal is determined as the intermediate shaft braking period;
[0117] The time from when the gear shifting progress signal is switched to the gear-in-progress state signal to when the gear shifting is completed during the current gear shifting period is determined as the main transmission gear-in progress period.
[0118] When the shift type is from gear to gear, the clutch of the AMT does not act during the shift process, and the front auxiliary box, input shaft, intermediate shaft and main box participate in the action. Therefore, in the shift event (the time period when the shift occurs) of the shift type from gear to gear, the characteristic time periods included may be the main box disengagement time period, the front auxiliary box shift time period, the input shaft speed-up time period, the intermediate shaft braking time period and the main box shift-in time period. Therefore, according to the state signal of the front auxiliary box shift solenoid valve, the state signal of the intermediate shaft brake solenoid valve and the shift progress signal, the main box disengagement time period, the front auxiliary box shift time period, the input shaft speed-up time period, the intermediate shaft braking time period and the main box shift-in time period of the shift type from gear to gear can be identified.
[0119] In this embodiment, the above conditions can reliably and accurately identify the shift types as the main gear disengagement period, the front auxiliary gear shifting period, the input shaft speed-up period, the intermediate shaft braking period and the main gear engagement period within the shift period from in gear to in gear.
[0120] In another embodiment, the gear shifting data includes at least one of the following: gear shifting type, number of gear shifting times, single gear shifting duration, clutch disengagement duration, front and auxiliary gear shifting duration, intermediate shaft braking duration, main gear shifting duration, input shaft speed-up duration, and main gear shifting duration.
[0121] The number of gear shifts is the number of gear shift events that occurred within a specified time period.
[0122] The single gear shift duration is the duration of a gear shift event, which is calculated from the gear shift start time and the gear shift completion time during the gear shift period.
[0123] The duration of characteristic time periods such as clutch disengagement time, front auxiliary gear shifting time, intermediate shaft braking time, main gear shifting time, input shaft speed increase time and main gear shifting time are calculated from the start and end times of each time period.
[0124] Exemplarily, after the shift data is counted, the shift data may be stored in a data table, as shown in Table 1 below.
[0125] Table 1
[0126]
[0127] As shown in Table 1, the target vehicle had three gear shifting events within the specified time period. Among them, there were two neutral to in-gear type gear shifting events and one in-gear to in-gear type gear shifting event. The single gear shifting duration of the gear shifting event with a gear shifting start time of 8:55:01 and a gear shifting completion time of 8:55:02 was 1s, and within the gear shifting duration of 1s, the clutch separation duration was 0.2s, the intermediate shaft braking duration was 0.4s, and the front auxiliary gear shifting duration was 0.1s. The single gear shifting duration of the gear shifting event with a gear shifting start time of 8:55:30 and a gear shifting completion time of 8:55:32 was 2s, and within the gear shifting duration of 2s, the clutch separation duration was 0s, the intermediate shaft braking duration was 0.3s, and the front auxiliary gear shifting duration was 0.15s. The single gear shifting duration of the gear shifting event with the gear shifting start time being 8:55:50 and the gear shifting completion time being 8:55:51 is 1s. Within the gear shifting duration of 1s, the clutch separation duration is 0.3s, the intermediate shaft braking duration is 0.4s, and the front auxiliary gearbox shifting duration is 0s.
[0128] In this embodiment, by counting the above-mentioned shifting data, the action duration of each AMT part in the shifting process can be subdivided and counted based on the shifting duration, which is conducive to the subsequent detailed analysis of the AMT hardware control performance and provides a detailed reference for the subsequent optimization of indicators such as shifting time and shifting smoothness.
[0129] For example, while storing the above-mentioned gear shift data, data such as the engine speed, road slope, throttle opening, etc. in each gear shift period may also be stored in association.
